thanks for comment, "建筑透视有些变形" because I shoot the picture with low angle, this is what I intend to make a stronger image of the building~~~~"色彩还原不错" although my olympus is not a DSLR, it is a prosumer digital camera, more convenient to use, and honestly that the lens is not worse than a DSLR len, only the CCD is not good enough as the DSLR.
